1 Each slot will auto select the proper speed for the card installed up to the maximum speed for the slot. Placing high
speed cards into slow speed slots will cause the card to be driven at the slow speed.
2 Slot is driven by a single rope and has a maximum speed of 66 MHz.
MP Core I/O Board
The SEU core I/O card is the same one used in the server chassis. Up to two core I/O cards can
be plugged into the SEU. Two core I/O cards enable two additional I/O partitions to be added
to the number of partitions that exist in the server attached to the SEU. Since the server can have
up to two partitions, the total number of partitions possible in a server with the SEU attached is
four partitions.
The core I/O card can be replaced with standby power applied. The system power to the core
I/O is handled in the hardware the same way a hot-plug PCI/PCI-X card is handled. Standby
power to the core I/O is handled by power manager devices to limit inrush current during
insertion.
Mass Storage (Disk) Backplane
Internal mass storage connections to disks are routed on the mass storage backplane, having
connectors and termination logic. All hard disks are hot-plug while removable media drives are
not hot-plug. The SEU accommodates two internal, removable media devices. Therefore, power
connectors for a removable media drive are required on the mass storage backplane.
